Safe water markers are also known as fairway buoys. They can come in many shapes and sizes, although they are usually ball-shaped or cone-shaped. They may have a red, flashing light at the top.
Safe water marks are often used to lay out a route in shallow waters so that boats can safely travel through. If the buoy has a specific waterway associated with it, the name of the waterway or route is pinned to it.Learn more about Crafts for Kids
